  • Patent number: 5392554
    Abstract: A multiple-point frame for mounting a self-aligning decoy. The frame provides multiple-points of attachment to the decoy thereby providing more stability and adaptability to various decoy body designs. A spindle having a concentrically mounted ball bearing is mounted on a stake, and further receives a sleeve in combination with the mounting frame. A ball bearing is also positioned within the sleeve so that when the ball be, axing mounted spindle is inserted within the sleeve, the friction between the two parts is substantially reduced. Consequently, the rotational movement about the spindle is enhanced.
